Given:

A material of dielectric constant 2 is inserted between the plates of a capacitor 3 micro F.

To find:

New value of capacitance ?

Calculation:

The general expression for capacitance (C) of a capacitor with a dielectric material (of Dielectric Constant K) placed inside it is given as :

 \boxed{ \bold{\therefore \: C_{(new)} = C_{(air)}  K}}

Putting the values in SI units:

 \implies \: C_{(new)} = (3 \times  {10}^{ - 6} )   \times 2

 \implies \: C_{(new)} = 6 \times  {10}^{ - 6}  \: F

 \implies \: C_{(new)} = 6  \:  \mu F

So, the new capacitance of the capacitor is 6 micro F.
